Ａ Novel Technique of Tacking Free Gingival Flaps to Soft Tissue Augmentation Surgery(Pin technique)

A dequate keratinized mucosa thickness is essential for the long-term health and esthetics of the peri-implant area. All along, for patients with soft tissue defects, FGG is the most commonly used treatment method. Although it can achieve better therapeutic effects, it also causes significant secondary injury areas. Objective : To achieve minimally invasive soft tissue augmentation without sutures, using tent pins to fix the soft tissue and ensure more reliable tissue stabilization. Materials and methods : This article describes a novel soft tissue augmentation technique that replaces conventional FGG with a combination of bone trephine and tack fixation. Results : All patients with this technique showed an improvement in their keratinized mucosal thickness in 1 month. No complications were observed, and all cases achieved tension-free healing and aesthetic outcomes. Conclusion : Pin technique has emerged as a reliable and predictable minimally invasive treatment approach for addressing insufficient peri-implant keratinized gingiva.
